2024 GMC ACADIA Engine Problems

In the process of taking my daughter to the emergency room I receive a dash notification on my recently purchased 2024 GMC Acadia "car overheating, possible engine failure". My gauges were within normal range and being that I was in an emergency I kept traveling. Leave hospital to head home the error message is gone. The following Monday, January 5th, heading in to work I receive the same error message on my dash "car overheating, possible engine failure". Drove to the nearest mechanic, left my car, and they discover a leak in the upper radiator hose. They call with bad news that the part is on nationwide back order. GM admitted to a faulty design, in the process of redesign. A SPAC case with a local GM dealership was opened. GM would expedite my case if I towed to a GM dealer. I would have to pay for the tow....

Apparently many vehicles like mine and including mine have defective radiator hoses or a poor set up with routing causing issues with the hoses. They are developing cracks/leaks causing poor circulation in the cooling system as well as possible engine failure. In speaking to mechanics and reading forum posts, it is evident that this is a large scale issue.

On a highway about an hour from home, my brand new vehicle with 5,318 miles on it, alarmed me to turn off the vehicle. I was going 75 mph. I pulled over and called GMC being that I just had an oil change and thought maybe they possibly didn't reset something. The vehicle said the oil pressure was low. The dealership advised me to check the oil. It was full and clean. The service person advised that I should be able to continue to drive. I then called my husband. Upon starting the vehicle it was making a noise coming from underneath the vehicle. He said do not drive that vehicle and he headed to come get me. We had it towed to a nearby dealership around 6 pm. I called GMC again because the tow truck driver could not figure out how to put the vehicle in neutral. The...

We have experienced multiple recurring issues with our 2024 GMC Acadia that raise significant safety concerns and affect the vehicle’s reliability and overall operation. First, the brake system exhibits persistent squeaking, even at low speeds or light applications. The dealership has inspected the brakes but the noise continues, raising concerns about premature wear or improper brake function. More concerning is the behavior of the automatic braking system while reversing. The system has repeatedly activated the brakes without any obstacle, vehicle, or person behind us. These unexpected braking events have created both physical and psychological stress for occupants and pose a real risk of causing a rear-end collision from another driver who may not anticipate sudden braking. Due to this hazardous condition, we have been forced to deactivate the automatic braking feature entirely, defeating a critical safety system the vehicle is equipped with. Additionally, the engine frequently runs rough during cold...

While 2 hours from home driving down the interstate with a full vehicle, the vehicle alarmed and the screen notified "No Oil Pressure, Turn Car Off Now". I pulled over immediately and we had to sit on the edge of the interstate for 45 minutes - a safety hazard for us and the surrounding traffic. The vehicle was towed to the nearest GM dealer, where they assessed the vehicle and advised that this is a known issue for 2024 and 2025 GMC Acadias and Traverses. The vehicle failed to move oil and the engine was seized - a significant safety hazard. After a month, GM has informed us that zero replacement engines are available in the world and there is no timeline for replacement or repair and the vehicle is unusable.

The Vehicles engine siezed at 6,400 miles leaving us stranded on the side of the freeway for 3 hours and GMC is trying to PIN the blame elsewhere. Car has been in the shop for 3 weeks and they are unsure if it will be covered by warranty. The only thing done to the car was an oil change performed at a GMC dealer.

My vehicle is 3 months old with 4650 miles. I was driving on the turnpike and without notice a warning on the dash advised that there was no oil pressure and to pull over. I had the vehicle towed to a dealer out of state since we were 3 hours from home. The dealer called today to advised the car needed a new engine. I asked what was the route cause and they advise the GM did not require the engine to be stripped to find one.
